Among stroke patients, primary intracerebral hemorrhage has the highest mortality rate. Expansion of hematoma plays a prognostic role in these patients. Although fluid levels have been shown to predict subsequent hematoma expansion, there are mimics of fluid levels that may confuse interpretation. We hypothesized that patients with true fluid levels on head computed tomography (CT) have higher hematoma progression rates and worse outcomes compared with patients who have fluid level mimics on CT. ⋯ A fluid level within intraparenchymal hemorrhage on head CT scan is associated with higher likelihood of intracerebral hemorrhage progression. However, this applies only to true fluid levels, with mimics having a lower likelihood of progression. A careful analysis of potential fluid levels is necessary before assigning prognostic implications.

The purpose of this report is to demonstrate the creation of a 4-rod lumbosacral construct, when "stacked" sacral-2-alar-iliac (S2AI) screws are not possible due to a concurrent treatment of sacroiliitis with a posterior approach sacroiliac joint fusion device. This technique uses a combined S2AI and subcrestal iliac approach to achieve the 4-rod lumbosacral construct, while simultaneously biomechanically supporting the S2AI screws and treating the sacroiliitis.

Properties and implementation of three-dimensional printed models in spine surgery: a mixed-methods review with Meta-Analysis.
Spine surgery addresses a wide range of spinal pathologies. Potential applications of 3-dimensional (3D) printed in spine surgery are broad, encompassing education, planning, and simulation. The objective of this study was to explore how 3D-printed spine models are implemented in spine surgery and their clinical applications. ⋯ Replicating realistic spine models for operative planning, education, and training is invaluable in a subspeciality where mistakes can have devastating repercussions. Future study should evaluate the cost-effectiveness and the impact spine models have of spine surgery outcomes.

Frameless robotic-assisted biopsy of pediatric brainstem lesions: A systematic review and meta-analysis of efficacy and safety.
Pediatric brainstem lesions are diagnoses that require tissue sampling to advance our understanding of them and their management. Frameless, robot-assisted biopsy of these lesions has emerged as a novel, viable biopsy approach. Correspondingly, the aim of this study was to quantitively and qualitatively summarize the contemporary literature regarding the likelihood of achieving tumor diagnosis and experiencing any postoperative complications. ⋯ The contemporary metadata demonstrates the frameless, robot-assisted biopsy of pediatric brainstem lesions is both effective and safe when performed in an experienced setting. Further research is needed to augment robot and automated technologies into workup algorithms.

Parkinson disease (PD) has been recognized as responsible for concurrent spinal disorders. Surgical correction may be necessary, but the complexity of such fragile patients may require specific considerations. We systematically reviewed the literature on degenerative spine surgery in patients with PD. ⋯ Degenerative spine surgery in patients with PD is challenging, with complications and revisions occurring in up to a third of treated patients. Surgery should be offered when other treatment options have proved ineffective and is typically reserved for patients with myelopathy or significant disability. Successful outcomes depend on strong interdisciplinary support to control the movement disorder before and after surgery.
